CROSSLINKABLE ACRYLIC RUBBER COMPOSITION AND CROSSLINKED ARTICLE

摘要

PROBLEM TO BE SOLVED: To provide a crosslinked acrylic rubber article which is excellent in tensile strength and undergoes little changes in tensile strength and tensile stress due to thermal load. SOLUTION: A crosslinkable acrylic rubber composition containing 100 pts.wt. acrylic rubber having units derived from an ethylenically unsaturated polycarboxylic incomplete ester (a) and units derived from a nonhalogenous unsaturated monomer (b) and 0.1-20 pts.wt. polyvalent amine crosslinker is cross-linked.
